ISO/IEC 80079-34:2018规定了建立和维护质量管理体系的特殊要求和信息，以根据证书制造Ex产品。虽然不排除使用与ISO 9001:2015目标兼容并提供同等结果的其他质量管理体系，但本文件给出了最低要求。 第二版取消并取代2011年出版的第一版，构成完整的技术修订版。与上一版相比的重大变化应视为轻微的技术修订。但是，为了符合ISO 9001标准，上一版的条款编号已发生变化: 2015年，正常“；重大变化表”；由于这个原因没有被包括在内。 本出版物以双标识标准发布。本标准应与ISO 9001:2015一起阅读

ISO/IEC 80079-34:2018 specifies particular requirements and information for establishing and maintaining a quality management system to manufacture Ex Products in accordance with the certificates. While it does not preclude the use of other quality management systems that are compatible with the objectives of ISO 9001:2015 and which provide equivalent results, the minimum requirements are given in this document. This second edition cancels and replaces the first edition, published in 2011, and constitutes a full technical revision. The significant changes with respect to the previous edition should be considered as minor technical revisions. However, the clause numbering in regard to the previous edition has changed in order to be in line with ISO 9001:2015. The normal “Table of Significant Changes” has not been included for this reason. This publication is published as a double logo standard. This standard should be read in conjunction with ISO 9001:2015
